Specification of Letters Patent.

' Application filed December 14, 1911. Serial No. 665,622.

To all whom it may concern Be it known that I, CHARLES J. MABTH, acitizen of the United States, residing at St. Louis, Missouri, haveinvented a new and useful Improvement in Gearing, of

which the following is a specification.

This invention relates to gearing, and is especially adapted for use inwashing machines and in washing machines and wringers combined, thoughit is useful in other combinations and for other purposes as well; andit consists of the novel construction, combination and arrangement ofparts herein shown, described and claimed.

My present invention is particularly adapted for use in operatingwashing machines and other machines which require operation alternatelyin opposite directions.

In washing machines of a well-known type, there is a cylinder arrangedto contain the articles to be washed; said cylinder being revolublymounted in a receptacle arranged to contain the water. Superior resultsare obtained ,by rotating the cylinder alternately in oppositedirections so as .to cause the articles to rub against the inner surfaceof the cylinder while being agitated by movement through the water.

Since my invention is especially adapted for use in operating washingmachines of the type referred to, I have illustrated one embodiment ofmy invention combined Wit-h such a machine.

An object of the invention is to produce an improved gearing in whichthere is a driving shaft arranged to berotated constantly in eitherdirection, and carrying two gears loosely mounted thereon and meshingwith another gearcontrolling the driven mechanism, in combination withimproved clutch mechanism, operating automatically,

y of said driving shaft and said Wringer or'.

when the drivin shaft is in operation to lock first one 0 said two gearsand then the other on said driving shaft, thereby caus' said drivenmechanismto be operated fiernately in o posite directions.

Other objects involve the use of the drivingshaft to operate othermechanism, such, for instance, as a wringer, and convenient clutchdevices for controllingthe operation other driven mechanism. Otherobjects and purposes 12. A rod 15 is supported in bearin of the inven.-tion will appear from the following description, reference being made tothe accompanying drawings, in which- Figure l is a plan view of oneembodiment of my invention applied to and combined with a washingmachine and wringer. Fig. 2 is an "end view of the washing machine andwringer showing the gearing in combination therewith. Fig. 3' is a sideelevation of the gearing, the tub and cylinder of the washing machinebeing in section, and the cover or case of the gearing being also insection. v

The washing machine of the type illustrated includes a receptacle 1adapted and arrangedto contain the water, and having attached to theinner side of one of the end walls thereof "a bearing2. The other endwall of the receptacle has a bearing in which a. shaft 3 is journaled. Asocket 4 is attached to the inner end of said shaft and is rotated withsaid shaft when the latter is driven by the gearing and drivingmechanism. 'l'he cyllnder 5, which is arranged to receive and containthe articles to be washed, has a trunnion 6 on one end to rest andrevolve in the bearing 2, and on its opposite end said cylinder has apolygonal trunnion or projection Tarranged to extend into andformlocking engagement with the socket 4. Thus the cylinder 5 will berotated with the shaft 3, and change in thedirection of rotation of theshaft 3 will also change the direction of rotation ofthe cylinder.

In the type of washing machine shown,

wringer mechanism 8 is supported by the receptacle 1. The shaft 9 of oneof the wringer rolls extends beyond the frame of the wringer and has asprocket wheel 10 loosely mounted thereon. *A clutch member 11 issplined on the shaft 9 and constitutes means for locking the wheel 10 tosaid shaft,

and is operable to release and permit said wheel to run idle whendesired. A spring 12 encircles the shaft 9 between the clutch l1 and theframe of the wringer and actuat'es said clutch member towardthe'sprocket wheel. A lever "13 pivoted on a support 14 PatentedOct.29,1912.

embraces the clutch member 11 between two i 1 arms of said-levensaidarms extendin into a groove in-said clutch, and is-opera' le to releasethe clutch in opposition to the spring 16 on: the wringerframe'and' hason its inner end a cam 17, The cam 17 is'close to the may be driven.

A hearing casting. 20 is secured to-one end of the receptacle 1 and ashort shaft 21 is revolubly supported thereby. The shaft 21 is the shaftfor driving the remainder of the gearing, including the partscoiiperati'ng with the wringer, and is provided with a belt wheel orpulley 22 whereby said shaft A small gear 23 (Fig, 1) is rigid on theshaft 21 and meshes with a relatively larger gear 24 which is looselymounted on a shaft 25 journaled in hearings in the bearing casting 20. Aclutch member 26 is slidably mounted on the shaft'25 and is operable tolock the wheel 24 to said shaft, or to release said wheel and permit thesame to rotate freely and loosely on said shaft, as desired. A spring 27which encircles the shaft 25 is effective to actuate the clutch toclosed adjustment. A lever 28 pivoted on the bearing casting has armsentering a notch in the clutch member and is operable to open the clutchin opposition to the spring 27. A rod 29 has a cam 30 similar to the cam17 for the purpose of operating the lever to open-the clutch said rodbeing provided with a hand wheel 31 for purposes of operation. Two-gears32 are loosely mounted on the shaft 25 and are in constant mesh with arelatively large gear 33 on the outer end of the shaft 3. A clutchmember 34is keyed on' the shaft 25 between the gears 32 and is slidablefrom engagement with the hub-of one of said gears to engagement with theother. A lever 35 pivoted at 36 has a yoke embracing and engagin theclutch member 34: and is operable to move said clutch member-from one tothe other of said gears 32. Assum-' ing that the clutch 26 is closed,the shaft 25 will be rotated by power applied to the wheel or pulley 22.The gear 32- which is engaged by the clutch 34: will also be rotatedandmwill drive the gear 33 and shaft 3, thereby rotating the cylinder 5.The lever 35 operates against a plunger or latch I device 37 yieldinglycarried in a support 38,

and is efiective to latch the lever and yieldingly hold the clutch 34closed with either one of the gears32, but will 'ermit movement of saidlever to move said clutch from one to the other of said gears.

A pinion 39 rigid on the shaft 25 meshes with a relatively larger gear40 revolubly mounted on a supportingaxle 41. i A pinthe yielding latchor clutch Wheel.

Loaaseo vbearing casting 20 above the shaft 25, so

that said shaft will be driven whenever the shaft 25 is rotated. Theshaft A l carries a casting 45 having two disks integral therewith, anda cam 46 integral with the inner face of each disk. The upper end of thelever'35 extends between the disks which carry the earns 46, and has aroller 47 to roll against the faces of the disks. shaft 25 is rotatedthe shaft 44 will also be rotated, and the cams 46'will operate thelever 35 so as to engage the clutch 34- with-the gears 32 alternately.The gears 32 being in mesh with the gear 33 on opposite sides of itsaxis will rotate the gear 33 in opposite directions. Thus, the shaft 25being in constant-rotation inone direction will automatically andalternately rotate the cylinder 5 first in one then in the oppositedirect-ion, such alternate operation being maintained continuously.-

The upper end of the plunger or latch '37 is wedgeshaped, and the lowerendof the -When the" direction and lever 35 is similarly formed, so thatthe ate said lever the distance required to completeclosing the clutch34 after said lever is started by the cams 46. It will be observed that,in the embodiment shown, the cams 46 are arranged to operate the leveronly partj of the dist'ance'required to move the clutch 3% from one gearto the other; and that the cams merely serve to open the clutch, whileto complete the movement of the lever to close the clutch. Therefore,there is a directoooperation between the clutch openers 46,

and the clutch c'loser '37 in eifectingthe reciprocal rotation of theshaft 3 and the cyl' inder r'ate the lever 28 and open the clutch 26 5.Manipulation of therod 29 to op stops and renders the gearinginefiective in so far as the operation of the shaft 3 and the clutchopening and closing devices are conerned.

The same power may be used for operating the wringer 8 eitherconcurrently with or independently of the gearing'fordrivin the shaft 3.Asprocket wheel/18 1s rigi with the gear'wheel 24 and rotates with saidsprocket 48 proper manipulation of thejrod 15 to open or closetheclutohllfthe wringer may be operated or maintained idle, as desired.

The entire gearing mechanism may be shielded and incased in a housing 50which is attached to and supported by the bearing casting 20. Thisprevents the clothing of the operator, and other articles, from becomingentangled in the gearing and is of material benefit where the gearin isemployed on washing machines and'o er machines where there isopportunity for and danger of entanglement.

I have shown my improved gearing combined with a washing machine towhich it is especially-adapted, but it is obvious that it may beemployed advantageously for operating any mechanism where reciprocatingor rocking or oscillating movements are required. I do not confinemyself to use of the invention in any particular embodiment orcombination.

I am aware that there may be variations and alterations in thearrangement of the parts, to meet difierent requirements and conditions,without departure from the nature and spirit and scope of the invention.I do not restrict myself to specific features, but contemplate suchchanges and adapta tions in arrangement and construction as will renderthe gearing most useful and serviceable for the purposes intended.
